MDA is designed as a test bed for an astrobiology field instrument to detect microbial metabolic activity in terrestrial or extraterrestrial geological soil samples. MDA employs electrochemical sensors in a unique differential chamber configuration, able to detect minute changes in the chemical composition between the two otherwise identical chambers. Both chambers are filled with identical aut...

The proliferation of Streptococcus faecalis var. liquefaciens on two varieties of beans, and on corn, rye, and cabbage was investigated. Comparisons were made with growth patterns on these same plants exhibited by S. lactis and Lactobacillus plantarum. The ability of each of the bacteria to multiply and to spread to new plant parts as they developed from seed was studied under several environme...

In this study, aimed to investigate the effect of bacterial fertilizer: A (Bacillus spp., Trichoderma spp. ), B (Azorhizobium, Azotobacter and Azospirillum) C (Azotobacter Bacillus Pseudomonas putida) on soil carbon mineralization. On application A, fertilizers sterilized control soil, whose initial mineralization rates is 1.1%, 5.12%, 3.54%, 10.78% were respectively recorded. According these r...

This paper analyzes the attitudes of low-income women towards abortion and contraception. A survey was conducted in 1992 with a total of 3,149 childbearing-age women living on the outskirts of the Greater Metropolitan São Paulo Area. The study focuses on a sub-sample of 583 women. Attitudes of sterilized and non-sterilized women are compared. Women, especially those sterilized, found the most i...

The impact of the aeration status soils on environmental fate soil-applied pre-emergent herbicide metolachlor is significance to sustainable agriculture practices and has not been investigated thoroughly by existing research works. To address this knowledge gap, we examined adsorption, desorption, degradation, mineralization radioactively labeled [14C] in Catlin, Flanagan, Drummer under aerobic...

Cacao (Theobroma cacao) is an important cash crop in tropical climates such as that of Latin America. Over the past several decades, the infection of cultivated cacao by Moniliophthllora roreri, known commonly as "monilia", has significantly hindered cacao production in Latin America. Studies have proposed the use of Trichoderma sp. fungi in biocontrol treatments to prevent and reduce monilia i...
